Hi all,
I have a question about IGMPv3 state machine. If a group is in EX(X,Y) and =
a TO_IN(A) is received, the new state according to the RFC is EX (X+A, Y-A)=
. I think this mean remove all the elements of A from Y and add all element=
s of A to X. This also implies that sources not removed from Y will still e=
nd up being added to X. My question is why cant we add only those elemets o=
f A to X which are removed from Y as opposed to adding all the elements of =
A to X ??
If only the elements that are removed from Y are added to X, the new state =
would look like EX (X+(Y*A), Y-A).
Am I missing something here??
